SANTA CLARA, Calif. (AP) Mike McGlinchey's first test as an NFL tackle came against one of the league's top pass rushers in Dallas' DeMarcus Lawrence.

Things will only get tougher this week when McGlinchey must contend with three-time former AP Defensive Player of the Year J.J. Watt and Jadeveon Clowney when the 49ers travel to Houston for two days of practice against the Texans before an exhibition game on Saturday.

"It's going to be fun. It's definitely going to be fun," McGlinchey said. "That's why you play in the NFL, to play against the biggest and the baddest dudes and they have three or four of them. It's going to be pretty fun. I'm more worried about the heat monster than those guys. As long as I can stay upright and not lose 15 pounds in practice, I'll come out a winner."
